Anterior Chamber Cell Detector (ACCDor)

This repository contains the code for ACCDor, an anterior chamber cell detector.

Installation

1. Create a new conda environment with Python 3.9:

conda create -n accdor python=3.9

2. Activate the conda environment:

conda activate accdor # sometimes could be `source activate accdor`

3. Install the required dependencies:

pip install -r requirements.txt

Checkpoints

ACCDor requires a pre-trained ViT model. Download the model from the ViT-H SAM model link. The link is provided in the SAM repository. Put the pre-trained model into the models folder

Getting Started

To process an image, segment the AC area, and detect cells, run the following command:

python -m apps.detect_cell

By default, this command will process the image located at data/example/example1.jpeg. The output will be saved in the data/output/{image_name} directory, where {image_name} is the name of the example image (in this case, example1).

Showcase

After running apps.detect_cell, intermediate stage images will also be generated. Below are examples of the generated images for the sample input image.
